VISTA AC

Single AC unit serving 2-story 1,200 sq ft paint store show room. Done on a 103 degree day. Immediately dropped interior air temp 7 degrees. Next day, also 103 degrees. Manager called and said it was 12 degrees colder than before the RCC was applied to the AC unit.

In most cases, water and a brush. If the surface area is filthy, oily, greasey, what works best is liquid tide with bleach. We will wet down the surface area, AC unit, metal roof etc, spray on liquid tide with bleach from a garden sprayer, scrub it, rinse it, let it dry. 100% environmentally friendly. Once dry, spot prime any rust. Spray or roller on the RCC. Cooling effect is immediate.

I have seen roof top units leak 45% on both supply and return. I have see the slitter between supply and return just rot with leaking air- conditioned air hits hot air than rains. Yours is more just color than sealing, black is 93% and white is 7% solar heat pick up. How much of that is from closing the outside air off?
